Isomag Bearing Isolator Installation Procedure on Paper Roll Machines

Share

The key here is to prevent angular movement of the shaft in relation to the housing during the installation/transportation process. Typically the roll is assembled with the housing in shop and then transported to its operating position by use of a crane. During this transportation process, it is critical to stabilize the shaft, maintaining alignment with the housing bore. This can be done by attaching wooden blocks that keep the shaft in line with the housing as shown in Figure 1. While it’s a crude solution, it works. If the wooden blocks are configured correctly (as shown in the figure) they will ensure the shaft stays in line with the housing, and therefore preventing the impact on the bearing isolators.
